Answer:

54.56

Step-by-step explanation:

Given:

Mean, u = 48

Standard deviation, \sigma = 4

Test score = 5%

Required:

Find the raw score, X.

Having a test score of 5% means the Zscore has to correspond to 95%, ie, 1 - 0.05 = 0.95.

Thus, Z_0_._9_5 = 1.64

To get X, use the formula:

mu + z * \sigma

= 48 + (4 * 1.64)

= 48 + 6.56

= 54.56

The anxiety test score that would put someone in the top 5% is 54.56
